I liked the look of that book @Celia and @Acorn but when I looked closely it's waaayyy beyond my sewing capabilities
I very much doubt that, Lowena.
Having now finished sewn my first quilt (another is in the early stages of construction), there’s a huge amount of planning, measuring and general faffing with a quilt and I think a basic fabric bag is actually a much easier and quicker project.
Debbie Shore has some great books and YouTube tutorials for newbie bag makers.
You could always start with a basic grocery type shopping tote, if you fancied giving it a try?
